Example 8-19 How the func function can return the symbol for a kernel space address
This example uses a bash script to pick a test symbol from
/proc/kallmodsyms that can be used as a reference in the DTrace program
that returns the symbols for the module and function.
#!/bin/bash
read ADD <<< $(awk '/ksys_write/ {print $1}' /proc/kallsyms)
dtrace -qn 'BEGIN {func(0x'$ADD'); exit(0)}'
